dolyame-ui-inputphonenpm
Advisory published Updated
dolyame-ui-inputphone is a confirmed malicious npm package (MAL-2026-13580) that executes malicious code on install (malicious version 35.8.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dolyame-ui-inputphone (npm)
What this malware does
On require() of the package, index.js loads runtime.js which downloads a platform-specific binary from a set of Cloudflare Workers endpoints (oob-worker.cf10x-*.workers.dev) with a DNS-TXT chunked fallback to sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. Host strings are reconstructed at runtime via array-join (e.g. ['sdk.dl.wel1','.ru'].join('')) to evade static scans, and API references are split (child'+'process, 'chmod'+'Sync'). The fetched bytes are written to a temp path with a cover-story filename (.cache_, dotnet_diag_.exe), chmod 0755 on Unix, and executed detached via cp.spawn('/bin/sh',['-c', filePath+' &']) or spawn('cmd',...) on Windows. No hash or signature verification is performed and the destinations are unrelated to the declared publisher. The package's own main export lib/telemetry.js, presented as a Sentry-like analytics SDK, wraps the same download/write/chmod/spawn primitives — the telemetry facade is cover for the dropper.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for dolyame-ui-inputphone (version 35.8.1).
If you installed it — respond
Remove dolyame-ui-inputphone from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If dolyame-ui-inputphone was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks dolyame-ui-inputphone-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
